Residents across Wantirna South, in the City of Knox, are being warned to expect disruptions to their home internet and landline phone services this week, as NBN Co carries out scheduled network upgrade works in the area.
What’s happening
Telstra has notified affected customers that NBN Co will be performing network updates in Wantirna South, with the interruption originally scheduled for 17 August 2026, running from 7:00am to 7:00pm. However, Telstra has cautioned that the maintenance date “may be subject to change,” with works set to go ahead at some point before 21 August 2026 — giving the disruption a potential window of almost a week.
The works will affect home internet (nbn) and home phone services for impacted Telstra customers in the suburb, which sits within the City of Knox local government area.
Emergency calls: use your mobile
Because the interruption affects landline phone services, Telstra is urging any affected residents who need to make an emergency call to dial 000 from a mobile phone, or use another alternative option, rather than relying on their home phone during the outage window.
Why it’s happening
NBN Co periodically carries out network upgrade and maintenance works to improve service reliability and performance in local areas. These planned interruptions differ from unplanned outages, as customers are notified in advance, though exact timing can still shift within the announced window.
What residents can do
- Check your mobile signal ahead of time in case you need it for calls during the interruption.
- Have a backup connectivity plan — such as mobile data or Wi-Fi calling — ready for the day works are carried out.
- Monitor Telstra’s outage page at outages.telstra.com for real-time updates on the status of works in your street.
- Visit tel.st/staying-connected for Telstra’s official tips on staying connected during service interruptions.
Stay informed
Knox residents affected by the works are encouraged to keep an eye on official Telstra and NBN Co channels for updates, as the scheduled date may change. Businesses relying on landline services or EFTPOS connections tied to the nbn network in Wantirna South should also plan around the announced window.
